Well up here we've less than a cm of snow! Practically most of Lancashire is unscathed although not more than 20 miles up north they've caught a packet in Cumbria.
Yes the Sunderland has been done. Folks need to look at the previous board as well as this one as we're seeing more duplicates. Sheriff's Harrier on wheels has already been done. Actually now both Phantom and Harrier have been draw four or five times.
The Sea Harrier (both FRS.1 and FA.2) on wheels has been done. There were some Harriers with U/C down on the original Photobucket site, but they're pretty bad. Wrong angle, wheels done badly. Some of the later Harrier drawings are major improvements on what has been around before.
See the attached. If that could seriously be called "duplication", I'll eat my hat.
